I was interested in purchasing a particular car from a used car dealership. Not ever having used Carfax, it gave me all of the information that I needed regarding what the car had been used for, any unnecessary things that were keeping me from making the final purchase not knowing just from looking at the car from the outside. It explained it in a way that I would understand if there were any prior accidents, flood damage and things that would end up costing me a fortune to have repaired. I would whole heartedly recommend Carfax to anyone who is considering purchasing a used car.
